Angelo Ochoategui, 13, said he was inside his home when he heard more than a dozen gunshots.

"Like 15 rounds," he said. "Then I checked outside. Someone knocked on the door. Everybody was banging on the door."

He said a group of males asked him to call 911.

"He said one person died and he was in 7th grade," Angelo said in a low tone.

Next, Angelo followed the group down the road to Cedartree Avenue and Baron Street, where he found someone bleeding out from a gunshot wound.

Investigators believe the teen that survived was trying to sell something online, and he arranged a meet-up. During that sale, two other teens showed up, and one of them pulled out a gun and shot him.

The teen shot back at the buyers, and they took off. While deputies were searching for the suspects, they found Hixon dead, along with 15-year-old Lamartine Malbranche and 16-year-old Jerry Murassaint.

Malbranche and Murassaint were arrested and are facing several charges including conspiracy to commit robbery, robbery with firearm, and murder while engaged in certain felony offense.

Malbranche and Murassaint were arrested in November 2018, suspected of breaking into cars and grand theft.
